Latch for a casement window

Thanks for reaching out to us. I'm afraid much of the design of the lock is obscured by the screen. Can you show us a photo of this lock removed from the window? That should allow us to narrow down some options. 

The 38-144 lock resembles what you show here. For compatible keepers, see the 38-276 and 38-277. Review the specifications and see if they match what you're searching for.
